What if the radio network could predict congestion before users experience it, adjust capacity automatically, reduce energy consumption during low-traffic periods, and help engineers identify the right action before service quality deteriorates?
That is increasingly the direction of AI-RAN — the application of artificial intelligence across Radio Access Network operations and optimization.
Traditional RAN operations depend heavily on thresholds, alarms, historical KPIs and engineer-driven analysis. AI introduces another layer: the ability to learn from network behavior, identify patterns across large volumes of data, predict potential degradation and recommend—or, under controlled conditions, execute—optimization actions.
But AI-RAN is not simply about automating the RAN.
The bigger opportunity is creating a network where AI and experienced engineers work together, combining machine-scale analysis with operational judgment, governance and network knowledge.
Why Does RAN Need AI?
At 8:30 PM, traffic begins climbing across a busy urban 5G cluster.
One cell is approaching congestion.
A neighboring cell still has available capacity.
Interference is increasing at the cell edge.
Some users begin experiencing lower throughput, while others continue receiving perfectly normal service.
Nothing is completely down.
But the network is no longer operating at its best.
Traditionally, RAN teams investigate such conditions through KPIs, counters, alarms, drive-test information, performance reports and optimization tools.
The challenge is scale.
A modern mobile network may contain thousands of cells, continuously producing performance information while traffic, mobility, interference and radio conditions change throughout the day.
AI can analyze these changing conditions together and identify patterns that would be difficult to recognize manually across such a large environment.
The value of AI-RAN is not simply automating another RAN task. It is helping the network understand changing conditions faster and respond more intelligently.
How AI-RAN Actually Works
AI-RAN starts with a simple idea:
The radio network continuously produces signals about its own condition. AI turns those signals into operational intelligence.
Instead of looking at one KPI or alarm in isolation, AI models can analyze multiple dimensions of network behaviour together.
1. Observe — Collect the Network Signals
The process begins with data from the RAN environment, including traffic load, throughput, latency, SINR, interference, mobility, resource utilization, alarms and historical performance.
This creates a continuously evolving picture of how the radio network is behaving.
2. Understand — Find the Pattern
AI analyzes relationships across this data to identify patterns that may not be obvious from individual counters.
For example, rising traffic alone may not be a problem. But rising traffic combined with deteriorating radio quality, increasing resource utilization and changing mobility patterns may indicate developing congestion.
3. Predict — What Happens Next?
The next step is moving from understanding the current network toward anticipating its future state.
Will this cell become congested?
Will customer throughput deteriorate?
Will additional capacity be required during the next traffic peak?
4. Optimize — What Should We Change?
Based on the predicted condition, AI can recommend an optimization action—for example, adjusting resource allocation, load balancing, mobility behaviour or energy-saving strategies.
Depending on the maturity and risk of the use case, the recommendation may be reviewed by an engineer or executed automatically within predefined operational policies.
5. Validate & Learn — Did It Actually Work?
This is one of the most important steps.
After an optimization is applied, the network must be measured again.
Did throughput improve?
Did congestion decrease?
Was customer experience better?
Did another KPI deteriorate?
The result becomes new information for future decisions.

Where Is AI-RAN Creating Real Value?
AI-RAN becomes meaningful when intelligence produces a measurable improvement in the live network.
The value can appear in different forms: higher throughput, better spectrum utilization, lower interference, improved energy efficiency, more accurate capacity decisions, or a more consistent customer experience.
Six areas are particularly important.
1. Intelligent RAN Optimization
Radio conditions can change within seconds.
Traffic moves.
Interference changes.
Users enter and leave cells.
Channel quality fluctuates.
Traditional rule-based algorithms are designed to respond to these conditions, but AI models can learn more complex relationships between network conditions and optimization decisions.
This makes areas such as scheduling, link adaptation, beamforming and resource allocation particularly interesting for AI-RAN.
Real Network Example — T-Mobile + Ericsson
In 2026, T-Mobile and Ericsson reported large-scale commercial trials of an AI-native Scheduler with Link Adaptation on T-Mobile’s live 5G Advanced network. Compared with legacy rule-based methods, the trial achieved up to 15% higher downlink throughput and close to 10% improvement in spectral efficiency.
2. Interference Optimization
Interference is one of the persistent challenges in radio networks.
The difficult part is that changing one parameter to improve one cell can affect neighbouring cells.
AI can analyze relationships across multiple cells and identify optimization opportunities that are difficult to capture through isolated threshold-based decisions.
This becomes particularly valuable in dense networks where traffic, coverage and interference continuously interact.
Real Network Example — KDDI + Ericsson
In 2026, Ericsson and KDDI completed a large-scale AI-driven uplink optimization field trial on KDDI’s commercial network across both 4G and 5G, demonstrating performance improvements while uplink traffic was also increasing. The trial was positioned as part of KDDI’s progression toward higher levels of autonomous network operations.
3. AI-Driven Capacity & Traffic Management
Capacity planning traditionally relies heavily on historical trends.
But tomorrow’s traffic does not always behave like yesterday’s.
A stadium event, transport hub, business district, holiday period or unexpected crowd movement can rapidly change demand.
AI can combine historical traffic, current utilization, mobility patterns and network behaviour to predict where capacity pressure may develop.
Instead of asking:
“Which cells were congested last month?”
the operational question becomes:
“Which cells are likely to become congested next?”
That gives RAN teams something extremely valuable:
time to act before capacity becomes customer impact.
4. AI-Powered Energy Optimization
A radio network does not experience the same traffic load 24 hours a day.
During low-demand periods, AI can help identify where selected network resources may safely enter energy-saving states while maintaining required coverage and service quality.
When traffic begins increasing again, resources can be restored dynamically.
This changes the objective from simply:
“Reduce energy.”
to:
“Use energy intelligently according to network demand.”
The business value is particularly important because energy optimization connects AI-RAN directly with OPEX reduction and sustainability objectives.
5. Customer Experience Optimization
A cell can technically remain available while some users still experience poor service.
AI-RAN can analyze radio conditions at a more granular level and help identify patterns affecting throughput, latency, coverage and user experience.
This allows optimization to move beyond:
“Is the cell healthy?”
toward:
“Are users actually receiving the experience the network was designed to provide?”
eal Network Example — Optus + Ericsson
In a 2026 Australian trial, Optus and Ericsson reported that AI-native RAN link adaptation delivered more than 20% cell-level throughput improvement in medium-to-poor radio-frequency conditions, without requiring additional spectrum or hardware.
6. Toward Self-Optimizing RAN
he most interesting stage appears when these capabilities begin working together.
AI detects developing congestion.
It predicts the likely impact.
It identifies an optimization opportunity.
A controlled action is recommended.
The network measures the result.
The outcome becomes feedback for the next decision.
That creates a closed intelligence loop:
Observe → Predict → Optimize → Execute → Validate → Learn
This does not mean every RAN change should become autonomous.
The level of automation should depend on risk, confidence, operational policy and the potential customer impact of the action.
But it shows where AI-RAN is ultimately heading:
from a network that follows predefined rules toward one that can increasingly adapt to changing conditions.
AI-RAN Is Already Moving Into Live Networks
AI-RAN is often discussed as part of the future of 6G.
But some of its most interesting capabilities are already being tested—and in some cases scaled—across live commercial 4G and 5G networks today.
The important shift is that operators are beginning to measure AI-RAN through actual network outcomes:
Does throughput improve?
Can spectrum be used more efficiently?
Can interference be reduced?
Can optimization scale across thousands of cells?
Recent deployments and trials provide some useful answers.
T-Mobile — AI-Native Scheduling at Scale
In May 2026, T-Mobile and Ericsson reported large-scale commercial trials of an AI-native Scheduler with Link Adaptation using live 5G Advanced traffic.
The AI model predicts rapidly changing radio conditions in real time and adapts transmission decisions accordingly.
The reported result:
Up to 15% improvement in downlink throughput
Close to 10% improvement in spectral efficiency
compared with legacy rule-based methods.
This is significant because spectrum is one of an operator’s most valuable assets. Improving spectral efficiency means extracting more performance from infrastructure and spectrum already deployed.
KDDI — AI Optimization Across Thousands of Cells
KDDI and Ericsson approached AI-RAN from another direction: uplink interference optimization.
Their 2026 commercial-network field trial covered approximately 1,500 5G cells and 1,300 4G cells.
Ericsson reported average throughput improvements of 9.6% in 4G and 3.1% in 5G, alongside a 27% improvement in 5G SINR.
What makes this example particularly interesting is scale.
AI optimization becomes much more valuable when it can move beyond a handful of test cells toward large multi-band, multi-technology network environments.
Optus — Improving 5G Without More Spectrum
In Australia, Optus and Ericsson tested AI-native Link Adaptation in challenging radio conditions.
The field trial reported more than 20% improvement in cell-level throughput under medium-to-poor RF conditions—without adding new spectrum or hardware.
That illustrates an important business case for AI-RAN:
Before asking how much more infrastructure should be added, ask whether intelligence can extract more value from what is already deployed.
AT&T — Bringing AI Into Cloud RAN
AI-RAN is also converging with Cloud RAN.
In 2026, AT&T and Ericsson demonstrated AI-native Link Adaptation on a Cloud RAN stack running on Intel Xeon 6 infrastructure, using AT&T-specific frequency bands and propagation characteristics.
This matters because it points toward a future where AI capabilities become increasingly portable across cloud-based RAN architectures rather than remaining tied to one fixed implementation.
SoftBank — AI-RAN Meets Physical AI
Another direction is emerging beyond network optimization itself.
SoftBank and Ericsson demonstrated a proof of concept combining 5G connectivity, AI-RAN-related edge computing and Physical AI workloads, allowing robotic systems to dynamically offload AI processing toward nearby edge compute resources.
This introduces a broader possibility:
The RAN may not only use AI to optimize itself—it may eventually help provide the distributed connectivity and compute environment required by AI applications.
AI-RAN is moving from “Can AI improve the radio network?” toward a more commercially relevant question: “Where can AI produce measurable network and business value at scale?”
The Bigger Shift: From AI for RAN to AI on RAN
Until recently, most conversations about AI and the RAN focused on one question:
How can AI improve the network?
Better optimization.
Better traffic prediction.
Better energy efficiency.
Better interference management.
Better utilization of spectrum.
But another question is emerging:
Can the RAN itself become part of the infrastructure that runs AI?
This changes the conversation significantly.
Instead of thinking only about AI for RAN, the industry is beginning to explore AI on RAN.
In this model, distributed telecom infrastructure could potentially support both traditional radio workloads and AI workloads closer to where users, devices, machines and applications actually generate data.

CONNECTIVITY + COMPUTE + AI
This is why AI-RAN could eventually become much bigger than another network-optimization technology.
The radio network already provides something extremely valuable: distributed infrastructure located close to users and devices.
If connectivity, compute and AI can increasingly coexist across that infrastructure, telecom operators may have an opportunity to move beyond providing connectivity alone.
And that raises a much bigger strategic question:
Could AI-RAN eventually create new revenue opportunities for telecom operators—not only operational savings?
From Network Efficiency to New Revenue Opportunities
Most AI-RAN discussions begin with operational efficiency.
Improve throughput.
Optimize spectrum.
Reduce energy consumption.
Automate network decisions.
These benefits are important because they can improve network performance while reducing operational cost.
But there may be a second, potentially bigger opportunity.
What if telecom infrastructure could also become distributed AI infrastructure?
Mobile operators already have assets that many AI companies need: nationwide infrastructure, connectivity, edge locations, data centers, cloud platforms and proximity to millions of users and devices.
AI-RAN could potentially bring connectivity, computing and AI processing closer together.
1. Edge AI Inference
Many AI applications cannot always afford to send every piece of data to a distant hyperscale cloud.
Industrial automation, video analytics, robotics, autonomous systems and immersive applications may benefit from processing closer to where data is generated.
Telecom edge infrastructure could potentially provide that environment.
Instead of selling only connectivity, an operator could eventually provide:
Connectivity + Edge Compute + AI Inference
as an integrated enterprise service.
2. AI Compute as a Service
Distributed telecom infrastructure may also create opportunities to make underutilized computing resources available for AI workloads.
The commercial model could gradually move from charging primarily for GBs, bandwidth and connectivity toward charging for combinations of connectivity and compute capacity.
This does not mean every base station becomes an AI data center.
It means the boundary between telecom infrastructure and distributed computing infrastructure may become less distinct.
3. Physical AI & Robotics
Robots, drones, industrial machines and autonomous systems need more than intelligence.
They need reliable connectivity, low latency and access to computing resources.
This creates an interesting role for telecom networks.
A robot could perform some processing locally, offload more demanding AI workloads to nearby edge infrastructure, and use the mobile network to maintain reliable communication.
In that scenario, the telecom network becomes part of the AI execution environment, not simply the transport layer.
4. Enterprise & Sovereign AI Infrastructure
Telecom operators also have another strategic advantage: they operate infrastructure inside national markets and under local regulatory frameworks.
As enterprises and governments become more concerned about data residency, security and sovereign AI, locally operated telecom and edge infrastructure could become increasingly relevant.
This could open opportunities for operators to participate in national or enterprise AI ecosystems beyond traditional connectivity services.
The commercial promise of AI-RAN may ultimately be bigger than making the RAN cheaper to operate. It could help transform parts of the telecom network into infrastructure on which AI services themselves are delivered.
What Could Slow AI-RAN Adoption?
The technical potential of AI-RAN is significant.
But moving from a successful trial to large-scale operational deployment is a different challenge.
For operators, the question is not only:
“Does the AI model work?”
It is also:
“Does it create enough value to justify deploying, integrating and operating it at scale?”
1. The ROI Must Be Measurable
A 5% or 10% improvement in a technical KPI sounds attractive.
But operators ultimately need to translate that improvement into business value.
Does higher spectral efficiency delay additional spectrum or capacity investment?
Does better optimization reduce congestion?
Does energy optimization materially lower OPEX?
Does improved radio performance reduce customer complaints or churn?
AI-RAN will scale faster when operators can connect technical improvement → operational impact → financial value.
2. AI Is Only as Good as Its Network Data
RAN environments generate enormous volumes of information, but more data does not automatically mean better intelligence.
Missing counters, inconsistent data, configuration differences, topology inaccuracies or poor historical records can weaken model performance.
AI-RAN therefore depends heavily on data quality, context and governance.
Before asking whether the AI model is intelligent enough, operators may first need to ask:
“Is the network data reliable enough for the model to learn from?”
3. Multi-Vendor Networks Make Integration Harder
Real telecom networks are rarely built from one technology generation, one architecture or one vendor.
Operators may have multiple RAN vendors, legacy technologies, Open RAN components, different OSS platforms and years of accumulated configuration.
An AI capability that performs well inside one isolated environment may be much harder to scale across the complete network.
This makes interoperability, common data models, APIs and open interfaces strategically important to AI-RAN adoption.
4. AI Itself Requires Compute and Energy
There is an interesting paradox in AI-RAN.
AI can help the network reduce energy consumption.
But AI models themselves require compute, accelerators, storage and power.
As AI workloads move closer to the network edge, operators will need to balance the intelligence gained against the infrastructure required to provide it.
The winning architecture may therefore not be the one running the largest AI model everywhere.
It may be the one using the right intelligence, at the right location, for the right operational problem.
The success of AI-RAN will not be measured by how much AI an operator deploys. It will be measured by how much network and business value that intelligence creates.
Where Does AI-RAN Go From Here?
The first generation of mobile networks was primarily about connecting people.
Later generations expanded that role—connecting smartphones, enterprises, machines, industries and increasingly complex digital services.
AI-RAN introduces another possibility.
The radio network may begin to evolve from infrastructure that simply carries data into infrastructure that can increasingly understand, optimize and potentially process intelligence closer to where that data is created.
In the near term, the strongest business cases are likely to remain practical:
Better spectrum utilization.
Higher network performance.
Lower energy consumption.
More accurate capacity decisions.
Improved customer experience.
These are measurable problems with measurable value.
But the longer-term opportunity could be much larger.
As RAN, cloud, edge computing and AI infrastructure converge, operators may eventually ask a different question.
Not simply:
“How can AI make our radio network better?”
But:
“What new AI services can our network enable?”
That is where AI-RAN becomes more than another optimization technology.
It potentially becomes part of a new telecom infrastructure model built around:
Connectivity + Compute + Intelligence
The biggest opportunity in AI-RAN may not be teaching the network how to operate better. It may be discovering what becomes possible when the network itself becomes part of the AI infrastructure.
